IMPROVEMENT IN BED-BOTTOMS.

Specification forming part of Letters Patent No. 146,!25, dated January 6, 1874; application filed October 17, 1873.

To all whom it may concern Be it known that we, JOSIAH J. DEAL and SAMUEL HOBBS, of Wilmot, in the county of Stark and State of Ohio, have invented an Improved Bed-Bottom; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings making part of this specilication- Figure l being a view of the under side of a bedstead having a bed-bottom constructed with our improvements 5 Fig. 2, a lon gitudinall vertical section of the same; Fig. 3. a t-ransverse vertical section of the bed-bottom, Fig.

4, a top View of one end of the bed-bottom detached; Fig. 5, a top view of one of the springs 5 Fig. 6, a side view of the spring.

Like letters designate corresponding' parts in all of the iigures.

The natureof our invention consists in an ilnproved construction of coiled springs,which support the slats of the bed-bottom, and in the mode of attaching the springs to the bed-bottom. The springs are constructed to be suspended, and the slats resting thereon are suspended thereby.

Each spring A is formed of a piece of wire, one end of which terminates in a hook, a, and continues iirst straight therefrom downward to form a central stem or shaft, b, from the lower end of which the coil c commences enlargin g in diameter from the lower coil till the requisite diameter is obtained, and at the upper end of the coil, which is of full diameter, the end of the wire extends radially inward at d, and is finally bent or coiled around the stem' b. This looped end d slides on the saidi stem as the spring is compressed. or expands, and thus furnishes a guide to keep the 4sprin g in a central and firm position. To make up a bed-bottom, the stem of each spring first eX- tends up through a hole in one end of a slat,

B, which rests on the upper iiat end of the hook a is raised from the rod E, and turned partly round, so as to disengage it oln the rod, when the spring can at once be removed.

Inside of each spring A, around the central stein b thereof, we place a block, g, of wood or other suitable material, to serve as a stop to the descent of the slat B, which will rest thereon, and thus be prevented from breaking or unduly bending the spring when too heavy `a weight or violence may come thereon.

We are aware that previous to our invention the state of the art showed'coiled springs suspended from bars by hooks at their upper` ends, the suspending shaft, hook, and coils being made from one piece of wire, and that coiled springs have been kept in a central position around separate xed rods'by guideends of the springs extended thereto 5 also, that stops of diiferent construction' have been used to limit the extent to which the springs may be depressed; therefore our improvements do not include any such construction.

What we claim as our invention, and desire to secure by Letters Patent, is

l. rlhe coiled spring A, constructed with the looped guide-end d, surrounding the` stem b, as well as with the hook a, stem b, and coilc, all the parts being formed of one piece ofwire, substantially as and for the purpose herein specified.

2. The combination of the hook-springs A` A, perforated suspending-bars O O, and sustainingrods E E, substantially as and for the purpose herein speciiied.

3. In combination with the suspended springs A A and the slats B B, resting thereon, the stops g g, suspended in the said springs, substantially as and for the purpose herein speci-
